Oh grow up.

Germany's not a great place for the chronically immature. A highway exit is called an "Ausfahrt." When you say "I don't want to," you say "Ich habe keine Lust" -- I have no lust.
And while "Lust auf eis" sounds kinda dirty, it just means "fancy ice cream." The best example I've some across, though, was from that day we rode the cabe cars in Rüdesheim, and it seemed like we were headed toward a proctologist's house.
